Professor Tina Wong is the Head and Senior Consultant of the Glaucoma Department at Singapore National Eye Centre. She was trained at the Moorfields Eye Hospital, London, UK. She combined her clinical training with academic research and was awarded the prestigious Wellcome Trust Vision Research Fellowship to pursue and complete a PhD at the Institute of Ophthalmology, University College London in Professor Sir Peng T. Khaw’ laboratory. The work of the thesis was in the areas of matrix metalloproteinase and conjunctival wound healing in relation to post-operative scarring from glaucoma surgery. Her research led to the award of the Founders Cup in the Oxford Ophthalmological Congress and the Moorfields Research Medal.
 
Professor Wong is the Head of the Ocular Therapeutics and Drug Delivery Research Group at the Singapore Eye Research Institute. She holds an adjunct faculty appointment at the National University Hospital System (NUHS). Professor Wong is the Executive Director of the National Health Innovation Centre, NMRC.
 
Professor Wong’s research interests lie in the development of new ophthalmic therapies , nanomedicine and the innovative application of drug delivery systems to improve on the current medical and surgical treatments in glaucoma and other ophthalmic diseases. Professor Wong has published widely in these areas and has nationally funded research grants amounting to $8M. She holds many patents to her name and is the co-founder of 2 spin off biotech companies that spawned from her research. One of these technologies was awarded the prestigious President’s Science and technology Award (Technology) in 2014. She is also the recipient of the MOH Clinician Scientist Award, the Asia Pacific Academy of Ophthalmology distinguished Service Award and the SingHealth GCEO Excellence Award.
 
Additionally, Professor Wong has presented at numerous international scientific and ophthalmological meetings and has also been invited as a speaker at international conferences as well as academic institutes and universities. She has supervised several PhD students from NTU, and graduate medical students from Duke NUS Medical School.
 
Professor Wong is the founding President of the Glaucoma Association of Singapore (GLAS), a member of the World Glaucoma Association, and examiner to the Royal College of Edinburgh of Surgeons (Ophthalmology), UK.
